AC Recharge Question

The dealer wants $200 to evacuate and recharge the AC system in an E90.

Has anyone had any experience with this? Does that price seem high?

Searched and couldn't find anything on pricing.

Thanks

Sounds reasonable. R-134a coolant is expensive and dealerships usually charge between $115 - $145 per hour. I'd expect they are charging you 1 hour of labor and $60 for refrigerant. I'd also check an independent shop for thier price. If they have the proper equipment to evacuate the system (which they should to be compliant with environmental laws regarding recycling of R-134a), then they should be able to do the job a bit cheaper - it's not rocket science.

I'm not sure how old your car is or how many miles, but you may want to get the dryer/filter replaced while your at it. It will add some cost, however.

If its weak, just charge yourself. Go to walmart and buy r134a with NO additional additives like stop leak. A 12oz can is about 12 bux. A recharge hose is about 10. Buy a meat thermometer and stick it in the center vent.

Burp the line before connecting the line to the low pressure valve. Run the system on max and open up the valve until the temp drops to 20 to 30 below ambient temp.

Only gas charge with can right side up. Shake the can to increase the evaporation of the r134a in the can if charging slows.

Question

How often do you usually charge the AC?
I don't drive that much these days. Thank You

It should never need to be charged. If it is not cooling because of a low refrigerant charge there is a leak that needs to be fixed.

A/C

It is good idea to recover and recharge,the main reason is to remove moisture from the system which is the biggest enemy.you need to turn your a/c every few weeks for few minute,to keep all the hoses and internal system lubricate and remove all the moisture to prevent premature break down.you cannot do it your self without proper machine..

I'm actually out of warranty and it turns out the condenser has a leak in it after running dye through the system.

I found a independent shop that specializes in foreign cars and they work on a lot of BMW's. They are doing the job for so much less that the dealer wanted, it's ridiculous. What the dealer wanted to charge for just the condenser alone before labor was absurd.

Just had a 2011 E90 335XI AC serviced. AC would freeze up on long trips. Refrigerant was low. Added refrigerant on the trip to get the AC back into operation. The refrigerant can came with a cheap pressure gauge, so that helped in doing the top up.

After returning home, had the dealer check the system for leaks and they found one of the Schrader valves had a slight leak. They evacuated the system, replaced both Schrader valves, and recharged. The service ticket:

Evacuate and recharge A/C system (with A/C repairs). $225.56 labor
17.21 2 x Schrader valves
14.72. R134 refrigerant

Plus an additional $25.75 for "shop supplies" and tax on all but the labor for a total of $286.72

They did the work in 1.5 hours while I waited at the BMW "SPA" in Alexandria, VA.

$286.72 to evacuate the system, replace two $5 Schrader valve cores that screw in and charge with $20 of refrigerant. If you do it yourself you can buy a nice set of gauges to keep and still save money.
